Commit 523847df1b37 ("pds_core: add devcmd device interfaces") included
initial support for FW recovery detection. Unfortunately, the ordering
in pdsc_is_fw_good() was incorrect, which was causing FW recovery to be
undetected by the driver. Fix this by making sure to update the cached
fw_status by calling pdsc_is_fw_running() before setting the local FW
gen.

In the event of a change in XGBE mode, the current auto-negotiation
needs to be reset and the AN cycle needs to be re-triggerred. However,
the current code ignores the return value of xgbe_set_mode(), leading to
false information as the link is declared without checking the status
register.
Fix this by propagating the mode switch status information to
xgbe_phy_status().

After failing to verify configuration, it returns directly without
releasing link, which may cause memory leak.
Paolo Abeni thinks that the whole code of this driver is quite
"suboptimal" and looks unmainatained since at least ~15y, so he
suggests that we could simply remove the whole driver, please
take it into consideration.
Simon Horman suggests that the fix label should be set to
"Linux-2.6.12-rc2" considering that the problem has existed
since the driver was introduced and the commit above doesn't
seem to exist in net/net-next.

from the driver name + VIF type + the unique id assigned at PCI
probe. The VFs are always removed on PF remove, so there should
be no issues with VFs trying to access missing PF structures.

Add in the periodic health check and the related workqueue,
as well as the handlers for when a FW reset is seen.
The firmware is polled every 5 seconds to be sure that it is
still alive and that the FW generation didn't change.
The alive check looks to see that the PCI bus is still readable
and the fw_status still has the RUNNING bit on. If not alive,
the driver stops activity and tears things down. When the FW
recovers and the alive check again succeeds, the driver sets
back up for activity.
The generation check looks at the fw_generation to see if it
has changed, which can happen if the FW crashed and recovered
or was updated in between health checks. If changed, the
driver counts that as though the alive test failed and forces
the fw_down/fw_up cycle.

Ideally there should not be any forward declarations here, which
would make it easier to show that there is no unbounded recursion.
I tried fixing this but could not figure out how to avoid the
recursive call.
As a hotfix, address only the broken prototype to fix the build
problem instead.

The existing implementation for non-Autonegotiation 10G speed modes does
not enable RX adaptation in the Driver and FW. The RX Equalization
settings (AFE settings alone) are manually configured and the existing
link-up sequence in the driver does not perform rx adaptation process as
mentioned in the Synopsys databook. There's a customer request for 10G
backplane mode without Auto-negotiation and for the DAC cables of more
significant length that follow the non-Autonegotiation mode. These modes
require PHY to perform RX Adaptation.
The proposed logic adds the necessary changes to Yellow Carp devices to
ensure seamless RX Adaptation for 10G-SFI (LONG DAC) and 10G-KR without
AN (CL72 not present). The RX adaptation core algorithm is executed by
firmware, however, to achieve that a new mailbox sub-command is required
to be sent by the driver.

Using the unified way to compare pointers and NULL, which cleans the static
warning.
eg:
if (skb == NULL) --> if (!skb）
if (skb != NULL) --> if (skb)

Follow the advice of the below link and prefer 'strscpy' in this
subsystem. Conversion is 1:1 because the return value is not used.

It's repeated with line 1793-1795, and there isn't any other
handling for it. So remove it.

When building with Clang we encounter the following warning:
| drivers/net/ethernet/amd/xgbe/xgbe-dcb.c:234:42: error: format specifies
| type 'unsigned char' but the argument has type '__u16' (aka 'unsigned
| short') [-Werror,-Wformat] pfc->pfc_cap, pfc->pfc_en, pfc->mbc,
| pfc->delay);
pfc->pfc_cap , pfc->pfc_cn, pfc->mbc are all of type `u8` while pfc->delay is
of type `u16`. The correct format specifiers `%hh[u|x]` were used for
the first three but not for pfc->delay, which is causing the warning
above.
Variadic functions (printf-like) undergo default argument promotion.
Documentation/core-api/printk-formats.rst specifically recommends using
the promoted-to-type's format flag. In this case `%d` (or `%x` to
maintain hex representation) should be used since both u8's and u16's
are fully representable by an int.
Moreover, C11 6.3.1.1 states:
(https://www.open-std.org/jtc1/sc22/wg14/www/docs/n1548.pdf) `If an int
can represent all values of the original type ..., the value is
converted to an int; otherwise, it is converted to an unsigned int.
These are called the integer promotions.`
